To all whom t may concern.'

Be it known that l, WILLIAM L. Wanmof Anoka, Anoka county, Minnesota, have invented certain new and useful Improve-v ments in Snowplows, of which the following is a specification.

My invention relates to a snow plow liavf ing a iexible connection with a source of motive power which will permit the plow to be. raised and lowered conveniently.

The plowlis used without material alter- Iation to tlietruck and does not in any way interfere with the cranking of the motor or with the 'steering mechanism of the truck. The invention consists generally in various constructions and combinations, all as hereinaftr described and particularly pointed out in the claims. In the accompanying drawings forming part of the specifications, p

Figure 1 is a plan view of a snow plow embodying my invention, looking at the underside thereof,

Fig. 2 is a plan view of the saine, Fig. 3 is a longitudinal vertical section,

showing the application of the snow plow l to a truck frame,

Fig. 4 is a side view of the snow plow, the forward portion of the truck being indicated in dotted lines,

Fig. 5 is a rear elevation of the plow,

Fig. 6 is a front elevation showing .the manner of attaching the plow to the lifting device on the truck frame.

In the drawings, 2' and represent the side diverging sills of the frame of the plow', having their forward ends secured and braced apart byva suitable means, such asa cross beam 4. I provide also the auxiliary braces 5 and 6 between the cross brace 4 and the sills 2 and 3. 7 and 8 are top plates arranged in parallel relation with the sills 2 and 3 at the top of the plow frame. These plates are pressed and held in their proper relative position by suitable supports, such as 9, 9a, 911,9, 9159s and ef: i1 and in and 12 and 12a are the forward and Aside push blocks against which the frame of the truck is seated when the plow is in use. The.

blocks 11 and; 11a are rigidly supported by the blocks 11 and l1a and the plates 7 and 8.

These blocks 11 and 11 receive the forward thrust or push of the bumper on the truck as it moves forward and the plow is forced along by thisfpressure'. The side thrust of the truck is taken up by the blocks 12 and 12, 15 and 15 represent kchains rigidly l connected to the plates 7 and 8 and 16 and 16 represent a tackle for hoisting and lowering the plow. 17 is a .suitable frame-work in which the tackle-supportinfbmechanism is mounted on the front of the truck, being supported vthereon by suitable means, such as a brace x18. 19 and 19 represent links pivotally connected to the auxiliary'braces 5 and Gand also having pivotal connections with the springs 2l of the truck by suitable means, such as'the clevices 22 and 22a.

23 and 23 represent mold-boards made of suitable sheets of metal and' securely bolted to the sills, plat'es and supports forming the frame of the. plow. 24 and 24E represent steel cutting,r shears, which are bolted to the.

lower portions of the moldboards and to the sills 2 and 3.A 25, 25a and 25b re resent shoes secured to the underside of t e sills and on which the plow is supported.

In operation, the plow .is ushed forward by the truck, sliding upon t e shoes 25, 25 and 25h. The bumper of the truck contacts with the forward and lateralpush blocks and the plow is thereby guided and held in so 'y its proper relative 'position with respect to cranking the motor. y

I claim as my invention:

l. The coinbinati.on,.avith a power pro`rpolled vehicle frame, of a snow prising a freine having rearwar ly diverg-` ing plow .wings and forward' and; lateral ush blocks mounted on said frame and hav- `ing seats for the"`forward portion of said the inclined braces 13 and 13 and blocks 10. and 10UL are horizontally mounted between'4 truckframe.

V2. The combinationywith a power pro'-` pelled vehicle frame, o' a snow vlowcomprising a frame having rearwar Aly diverging plow wings and forward and laterall push blocks mounted on said frame and hav l y portion is carried forward by the thrust of the links 19 and 19"..

low comire ing seats for the forward portion of said truck frame, an unobstructed space being provided between said push blocks and in. the rear of the apex of the plow, for the purpose specified.

The combination, with a truck frame, of a snow plow havingr diverging wings,

f blocks mounted inthe upper portion of said plow and against which the truck frame is seated, nd ineans.tlexibly connecting the lowerpdrtion of said plow with said truck for imparting a forward thrust to the lower portion of the low.

4i The combination, with a power propelled vehicle, of a snow plow having 4diverging wings, the upper portion of said plow having seats thereon for the forward portion of said vehicle frame, rods pivotally connected with said truck and the lower por-v tion of said plow for imparting a forwardthrust thereto, and means mounted on the vehicle frame for lifting said plow.

5. The combination, with a power pro-- pelled vehicle, of a snow plow having divergin g side win push blocks mounted on said p owa flexible 'metallic bar secured to said push blocks and against which the forward portion of the vehicle frame is seated, and means connecting the lower portion of the plow with said vehicle frame through which a forward thrust from the vehicle is imparted to said plow.

6. The combination, with a power propelled vehicle, of a snow plow having diverging side wings, push blocks mounted in the upperportion of the 'frame of the plow and against which the forward portion of the vehicle frame is seated, rods having a pivotal connection with the vehicle and projecting forwardly and downwardly and piv-v novatos impact thereof, and thrust Arods connected 'with the vehicle and projecting forwardly and downwardly therefrom and pivotally connected with said frame and transmitting the forward and downward thrust from the vehicle to said fraine and wings.

8. The combination, with a power propelled Ivehicle, of a snow plow frame having diverging wings and shoes at the apex and ends of said wings and adapted to rest and 'slide upon the ground, said frame having a seat in its upper portion for Contact with the frame of the vehicle to receive the pushing impact thereof, and thrust rods connected with the vehicle and projecting fory wardly and downwardly therefrom and pivotally connected with said frame and transmitting the forward and downward thrust .from the'vehicle to said frame and wings, a

cable connected with the plow frame and a hoisting device'mounted on the Vehicle for raising the plow to an inoperative position.

9. 'The combination,` with xii,- wer-propelled vehicle,of a snow-plow aviiig diverging side wings, push blocks mounted in f* the upper portion of the frame of the plow and againstiwhich the forward portion of the vehicle frame is seated,y rods having a pivotal connection with the springs of the vehicle at their rear ends and projecting forwardly and downwardly and pivotally connected at their forward -ends with the frame of the plow for exerting a downward and forward thrust thereon when the vehicle is in motion.

10. The combination, with'a power-propelled vehicle having a frame projecting in front of the tractionwheels, of a snow-plow having diverging side wings and provided with a frame having seats for the forward end of said vehicle frame., said seats being near the top of the plow and the vehicle eX- erting a forward pushing movement thereon, andl thrust rods pivotally connected at their rear ends with the frame of the vehicle ,and extending forwardly and downwardly therefrom and having a pivotal connection with the lower portion ofthe frame of the plow.
